    GPS and Hub Dynamo

    I'm planing next year to cycle for 3 months in Europe, starting in Lisbon and finish at my sisters place in Switzerland.
    I brought myself a Vivente World Randonneur touring bike with a front hub dynamo 6v-3w.
    My question is, has anybody used a dynamo for charging a GPS with it. If yes, what was the set up you used. Is it possible to buy some gear made up and ready to use. Maybe somebody has some idea what I have to get to make it myself.
    Any idea will be great.

    There is also Dahon Biologic Reecharge. When first responding, I was unaware that Reecharge was already available in retail.

    Doesn't the E-week also need a battery if you're hooking it up to an Iphone or such? I had posted a thread asking for feedback about the Recharge (which looks like an all-on-one with no dials to fiddle), but I didn't get any responses. Maybe it hasn't been out long enough, but it'd be nice to know a little more about both from folks who've used them.

    Sorry if I'm hijacking.

    newbie..you Can charge a GPS..order a Dahon Biologic Reecharge..know this though..the battery they use on the unit is 1600 Mah...you need a GPS with less then that or it won't charge right..I tried my Droid and it draws 1490 and it wouldn't charge except if you were going above 12 MPH,which is hard to maintain...need a GPS about 1000 Mah or less..lucky they are easy to find..you can charge your phone too but the same thing applies with the power...

    Like mentioned would depend on the GPS and its charging rate. I know my iPhone is quite fussy about what powers it. If I had a dynamo hub I would charge batteries and then transfer power to phone. Batteries can also do all kinds of other tasks you may need power when not riding.

    I use this device from Tekkeon http://www.tekkeon.com/productcart/p...&idproduct=194
    It can be used in a lot of different configurations ranging from alkaline to re-charge AA cells has both USB in and out and works with AC as a charger. So I carry 4 re-charge AA and 4 alkaline AA and this unit. If I had a dynamo I would likely skip the alkaline and just keep the re-charges topped off.

    I use the Tekkeon with one of those little USB lights as a tent task light also. Here is a picture of my setup other than the phone I used to take the photo.
